[Users] Call Forwarding using uac_redirect

[Bogdan-Andrei Iancu]

Hi Brandon,

get_redirects can be used only from failure_route since it process a 
negative (3xx) reply - see example:
    http://www.openser.org/docs/modules/0.10.x/uac_redirect.html#AEN247

the function fetch the contacts from 3xx and adds them as branches to 
the transaction. Once set as branches, the URIs can not be altered 
anymore - so you cannot change the contact between "get_redirects"  and 
"t_relay".

regards,
bogdan
